How Long Do You Grill A Sirloin On Each Side?
It depends on the thickness of the sirloin steak and how you prefer it cooked. A rule of thumb is to grill the steak for 4-5 minutes per side for medium-rare, 5-6 minutes per side for medium, and 6-7 minutes per side for well done. However, the best way to determine the doneness is to use a meat thermometer and cook the steak to an internal temperature of 130-135°F for medium-rare, 140-145°F for medium, and 150-155°F for well done.
